Question

我有UIWebView我想在其中加载链接，但它没有显示任何东西这里是我使用它的代码不显示

fileName的值为http://www.google.com

            NSURL *url = [NSURL fileURLWithPath:fileName];

    NSURLRequest *request = [NSURLRequest requestWithURL:url];
    [webView setScalesPageToFit:YES];

    [webView loadRequest:request];

Answer 1

尝试这样做，将fileURLWithPath替换为URLWithString

    NSString *fileName= @"http://www.google.com";

    NSURL *url = [NSURL URLWithString:fileName];

    NSURLRequest *request = [NSURLRequest requestWithURL:url];
    [webview setScalesPageToFit:YES];

    [webview loadRequest:request];

Answer 2

如果有包含您网址的路径，则会使用

**fileURLWithPath**。

但是在你的情况下，有一个直接的URL，所以你应该使用如下

 NSURL *url = [NSURL URLWithString:[NSString stringWithFormat:@"%@",@"http://www.google.com"]];

NSURLRequest *request = [NSURLRequest requestWithURL:url];
[webView setScalesPageToFit:YES];

[webView loadRequest:request];

Answer 3

//Create a URL String.
NSString *urlString = [NSString stringWithFormat:@"http://www.google.com"];
//Create a Legeal URL object.
NSURL *MyUrl = [NSURL URLWithString:[urlString stringByAddingPercentEscapesUsingEncoding:NSUTF8StringEncoding]];
//URL Requst Object
NSURLRequest *requestObj = [NSURLRequest requestWithURL:MyUrl];
// set Fit page to WebView
[webView setScalesPageToFit:YES];
//Load the request in the UIWebView.    
[webView loadRequest:requestObj];

注意：如果您使用webView添加，请不要忘记将self.View添加到XIB 或，然后确保您连接是正确的;
